Hello followers! Well I am back at it again with a post much sooner than last time. I am sad to say this will be my last post for quite some time, I have decided to step away from my work for the summer and enjoy the time with my children because they are only young for so long. My youngest son, Eli, is actually the reason I am writing today, he is always getting into trouble and getting cuts and scratches. So today I will be talking about a few products being created to improve wound care and create a more rapid approach.
Xiaolei Wang and colleagues at NanChang University in China have been working on a project to create and bandage that will burst and release an antibacterial capsule upon applying pressure. The capsule will act to create three distinct modes being packaged, on, or off. The idea is to take “silver nanoparticles and enclose them in a carbon membrane” (Woolford). The idea behind this is to create a supply system of antibacterial agents so limit the adaptions made by bacteria. The bandages will have two parts, (demonstrated in the image) an upper layer that will contain phosphate buffered saline while the bottom layer with holding the capsule.
The second article I reviewed was written by Jamie Durrani discussing a new material developed with the potential to heal its self at 37°, which is body temperature! This is a great innovation within the biomedical community, creating extensive possibilities for healing wounds. This can be useful in regenerative medicine!. Not only can it be used on damaged skin but also paints and mobile devices. The polyurethane materials upon being cut, will form back as one. It has a structure composed of many molecules so when they are disrupted, the viscosity, or thickness, is decreased. When the temperature is elevated, the molecules will separate providing for easy and relatively painless removal making it effective for human skin. (Durrani)
I correlated the two articles because of the healing properties they both possess, whether it be for minimal or extensive wounds. It is important to recognize they contain a supramolecular substance. A supramolecular substance is one composed of several molecules, in the case of the bandage it is the carbon membrane holding the antibacterial silver nanoparticles. In the case of the self-repairing polymer it is the polyurethane. Both of these products have potential to be used widely in future medicine and could be used greatly in hospital, military, and more treatment.
These two articles can be further connected with a third article which covers the idea of using fish skin to dress wounds. The active agent in the fish skin is collagen has created faster healing of wounds on mice used as the test animals. Tilapia often have pure proteins as compared to pig and cows whom can often have impurities. The collagen is extracted to create a sponge which is then spun into nano fibers. This topic is not as far in its research and testing as the other two but has great potential to be used in medicine.
Well this is a goodbye! Have a great summer! I wish everyone the best in their endeavors, particularly within chemistry! It has been a great ride. Signing off,
